See also xilinx_load_device_tree:

        /* Try the local "ppc.dtb" override.  */
        fdt = load_device_tree("ppc.dtb", &fdt_size);
        if (!fdt) {
            path = qemu_find_file(QEMU_FILE_TYPE_BIOS, BINARY_DEVICE_TREE_FILE);
            if (path) {
                fdt = load_device_tree(path, &fdt_size);
                g_free(path);
            }
        }
